Testing Biological Models for Non-linear Sensitivity with a Programmability Test

Hector Zenil, Gordon Ball, Jesper Tegnér

Abstract (Excerpt)

We address the question of what kind of test could be implemented to establish
whether an artificial system is living or not with a computability and programmability
test as advanced in [2]. We claim that necessary conditions for
life are non-linear behavioural variability and sensitivity to external stimuli.
